I think it depends where you are in the cycle. If you just finished putting in 50hrs of work, and have so far made $100, I wouldn't consider that true passive income. Fast-forward a year, and your income from the site has surpassed $2500 (the equivalent of your salaried wage for those hours), with minimal additional effort - now you are making passive income.

We're just defining words here anyway. I think a core component of what people think of when they think "passive income" is making a disproportional amount of income relative to effort put in. Until those proportions get dis'ed, you're just working at a sub-optimal job.
